The organisation is now applying to the State Government for $100 thousand in relief funding for a marketing campaign to encourage people to visit the area.

Executive Manager, Sheridan Ferrier says income losses across a five-day period equated to more than $4.7 million for the local industry.

"It contributed to loss of bookings and cancellations," she said.

"So straight away after I think the first day of heavy rain where there were reports in the area that the roads were closed immediately people started changing their travel plans."

Ms Ferrier says visitors need to know the area is still open for business.

"What we've found with other disaster areas is it takes at least three months before visitors start to come back into that region," she said.

"So we really need to get a campaign out to market to tell people that the Upper Hunter and Barrington Tops are still open for business and so that they don't change their holiday plans with the upcoming July school holidays."
